Please contact us and tell us about it. We review new prospects starting in September each year. A decision for inclusion is is based on value to the hiker and available space.

Each year we gather reroute information all during the year and then wait for the ATC to release their final mileage to compare and make any last minute adjustments. This final piece of information comes in at Thanksgiving each year. This is why, while our updates are finished by October, the A.T. Guide historically doesn’t ship until mid-January. In 2021 supply chains and print lead times became slower than ever and we had to make the decision to go to print much earlier in order to avoid extraordinarily late shipping dates. This means we have to make our calculations before ATC releases their “official” mileage. In many ways this makes us work harder to make sure everything is correct. We still get the official number from ATC around Thanksgiving but we have to wait for actual data in January. Anything we may have missed we post in the PDF and on our online updates page. A pleasant side effect of this process is the PDF is immediately available for download in November and the A.T. Guide books arrive in time for Christmas shipping deadlines. Rest assured, anything we might miss as a result of our new process is small and confined to local areas on the trail.

2023 Difference Explained

1. The bulk of the difference between our mileage and The ATC official mileage is in NY. We were aware of, and make specific mention the Palisades Parkway detour. ATC actually put +3.0 mile number to it.
2. We included the Forth Mountain Relocation.
3. We included the remeasures for Mass & Connecticut. There were a few places where we had to guess how ATC might round up or down to the next tenth of a mile because it was right on the edge.

Windows phone users will need to continue using a third party PDF reader.

The one thing we can not do is move any annotations you have made in a third party app to our app. So, if you have made lots of notes, you may want to stay with your current app or be prepared to transfer your annotations over manually.

It’s very easy. Download the app and log in using your TheATGuide.com username and password and the app will pull your PDF purchase in, ready to use. We have made several short tutorial videos to help you maximize the features of the app.

No. If you are pleased with your current reader, you may continue to use it. You may also continue to download your PDF from your user account and use your desktop PDF reader. Our reader is simply an additional tool at your disposal.

2021 PDFs and newer are viewable in the PDF Reader by logging in to your TheATGuide.com account. In order to ensure hikers are using the most recent information and guidelines for the A.T., we recommend using the most up to date guide for your hike. You may still use your older PDFs on your desktop device.

We have optimized this reader for our users giving us better control over our users PDF experience. If there is a problem, we can fix it. If we release a new feature, we can optimize it… a challenge we could not meet with third party apps.

No. The reader itself is a free download. You may purchase the PDF directly through the app or at TheATGuide.com.
